OSHA Hazard Communication Standard:
Communication Standard.
3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: A clear, colorless liquid with relatively no odor. Harmful or
may be fatal if swallowed. Harmful if inhaled. May cause skin and eye irritation and/or
burns. Not flammable.
POTENTIAL HEALTH HAZARDS
May cause irritation and/or burns, especially with prolonged contact.
SKIN:
May cause severe irritation and/or corneal damage (burns).
EYES:
Inhalation of mist may irritate mucous membranes, nose, throat and lungs.
INHALATION:
May cause severe damage to mouth, esophagus, and stomach. May be fatal. May cause
INGESTION:
kidney damage and hypocalcemia, possibly severe, due to the fluoride content, which
precipitates calcium stored in the body.

Stannous Fluoborate Solution
DELAYED EFFECTS: There is no chronic toxicity data on this material, however, NIOSH links inorganic
fluoborates with inorganic fluorides. Chronic exposure to fluorides is associated with
osseous fluorosis 鈥? increased radiographic density of bones, mottling of teeth, etc.
These conditions will not develop if permissible exposure levels are not exceeded.
Ingredients found on one of the three OSHA designated carcinogen lists are listed below.

4. FIRST AID MEASURES
Promptly wash with plenty of soap and water, then flush with water until all chemical is removed. Get
SKIN:
medical attention for any irritation. Promptly remove contaminated clothing and wash before reuse.
Immediately flush eyes with large quantities of water for 15-20 minutes, holding eyelids open to allow
EYES:
thorough flushing. Get medical attention for potential corneal damage.
Remove to fresh air. If breathing is difficult, give oxygen, provided a qualified operator is available.
INHALATION:
If not breathing, give artificial respiration, preferably mouth-to-mouth. Get medical attention if
symptoms persist.
Do not induce vomiting. If conscious, give several glasses of milk or other calcium-containing
INGESTION:
liquids, or several ounces of milk of magnesia, if available; otherwise, give large quantities of water
and get immediate medical attention.
Fluorides can reduce serum calcium levels resulting in potentially fatal hypocalcemia.

EXTINGUISHING MEDIA:
Use foam, carbon dioxide or dry chemical. Do not use water stream directly on material itself. Use water spray to
absorb or disperse vapors.
UNUSUAL FIRE AND EXPLOSION HAZARDS:
High temperatures yield mists containing toxic stannous fluoborate, which is corrosive to skin and some metals.

MATERIAL SAFETY DATA SHEET
Stannous Fluoborate Solution
SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
Avoid breathing vapors from burning material. Avoid bodily contact with the material. Wear NIOSH-approved self-
contained breathing apparatus. If contact with the material is anticipated, wear full protective clothing. Use water
spray to keep fire-exposed containers cool.
6. ACCIDENTAL RELEASE MEASURES
IN CASE OF SPILL OR OTHER RELEASE: (See section 8 for recommended personal protective equipment.)
Contain spill with readily available material (earth, sand, etc.) and recover if possible. Otherwise, neutralize with
sodium carbonate or other alkali and, using caution, flush with water, if permitted by applicable disposal
regulations. Keep out of sewer. Mop or pump into a suitable container, cover and label for storage and later
disposal. Provide personal protection for personnel involved with clean-up.
Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding
reporting requirements.
7. HANDLING AND STORAGE
NORMAL HANDLING: (See section 8 for recommended personal protective equipment.)
Do not get in eyes, on skin or on clothing. Avoid breathing mist, if formed. Observe good personal hygiene and
good housekeeping practices. Wash thoroughly after handling. Use with adequate ventilation and do not eat or
smoke while handling.
STORAGE RECOMMENDATIONS:
Store at moderate temperatures out of the sun in a dry, well-ventilated area, away from foodstuffs. Keep
containers tightly closed and protect from physical damage.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS:
If misty conditions prevail, provide local exhaust ventilation or a ventilated closed system (e.g., hood). Natural
ventilation is normally adequate in the absence of misty conditions.
PERSONAL PROTECTIVE EQUIPMENT
Wear impervious apron and gloves for routine product use. For increased
SKIN PROTECTION:
protection, if repeated or prolonged contact with liquid is anticipated, wear
impervious jacket and trousers. Promptly remove and wash items upon
contamination.
Under normal working conditions, wear chemical safety goggles; add a full-face
EYE PROTECTION:
plastic shield if solution may be splashed or sprayed and there is any possibility of
liquid contacting eyes. Do not wear contact lenses.

MATERIAL SAFETY DATA SHEET
Stannous Fluoborate Solution
For low levels of mist (<10 x TLV), use a NIOSH-approved dust and mist respirator.
RESPIRATORY
For intermediate levels of exposure (>10 x but <100 x TLV), use NIOSH-approved,
PROTECTION:
full-face, air cleaning respirators for both lung and eye protection. For high levels,
use NIOSH-approved self-contained or supplied-air breathing systems.
Provide eyewash stations and quick drench shower facilities near work areas.

INCOMPATIBILITIES:
Stannous fluoborate solution is acidic and will react with acid-incompatible materials, e.g., cyanides, sulfides.
It may react vigorously with strong oxidizing agents.
HAZARDOUS DECOMPOSITION PRODUCTS:
Stannous fluoride, boron trifluoride gas (speculative).
